Paragraph 166 Apparatus of National Grid in affected streets

Where any street is stopped up under article 13 (power to alter layout etc. of streets), article 11 (street works), article 17 (access to works), if National Grid has any apparatus in the street or accessed via that street National Grid has the same rights in respect of that apparatus as it enjoyed immediately before the stopping up and the undertaker must grant to National Grid, or procure the granting to National Grid of, legal easements reasonably satisfactory to National Grid in respect of such apparatus and access to it prior to the stopping up of any such street or highway but nothing in this paragraph affects any right of the undertaker or National Grid to require the removal of that apparatus under paragraph 257 (removal of apparatus) or the power of the undertaker, subject to compliance with this sub-paragraph, to carry out works under paragraph 259 (retained apparatus: protection).

Notwithstanding the temporary closure or diversion of any highway under the powers of article 16 (temporary prohibition or restriction of use of streets and public rights of way), National Grid is at liberty at all times to take all necessary access across any such closed highway or public right of way and to execute and do all such works and things in, upon or under any such highway as may be reasonably necessary to enable it to maintain any apparatus which at the time of the closure or diversion was in that highway or public right of way.
